一种二氯四氨钯固体结晶的制备方法
摘要：
本发明公开了一种二氯四氨钯固体结晶的制备方法，包括以下步骤：(1)酸浸溶解；(2)盐酸赶硝；(3)氨水络合；(4)酸化；(5)氨水溶解；(6)脱水结晶；(7)干燥。本发明一种二氯四氨钯固体结晶的制备方法通过加入脱水剂结晶得到产品，避免了传统制备工艺中，产品在蒸发浓缩过程出现过度的脱氨脱水，脱水剂在室温条件下加入，不需要加热浓缩，能够简化生产工序，提高产品纯度及产率。
摘要（英）：

The invention discloses a tetraammine dichloropalladium solid crystal preparation method, which comprises: (1) acid leaching dissolution; (2) nitre removing with hydrochloric acid; (3) complexing withammonia water; (4) acidification; (5) dissolving with ammonia water; (6) dehydrating crystallizing; and (7) drying. According to the invention, the product is obtained by adding the dehydrating agentthrough crystallization, so that the excessive deamination and dehydration in the evaporation and concentration process of the product in the traditional preparation process can be avoided; and the dehydrating agent is added under the room temperature condition, so that the heating concentration is not needed so as to simplify the production process and improve the product purity and the yield.
